Using vector search in Windows

[deepakbkar]

I was able to follow the steps for building faiss and use Bleve for vector search on Linux.

On Windows, I was able to build faiss libraries which produced faiss.dll, faiss.lib and faiss_c.dll.
On building my main.go (same code used on Linux), I am getting linker errors. I investigated this and can see that the faiss_c.dll does not have these functions exported.

I wanted to know if anyone has tried using vector search on Windows 11 and if there is anything I can try to make this work.
Any suggestion or ideas here will be useful.

Please let me know if you need more information.

@deepakbkar I believe this has to do with the DLL you've built using faiss. You must make sure you checkout the advertised version of faiss to build the dynamic library - https://github.com/blevesearch/bleve/blob/master/docs/vectors.md#pre-requisites

The code the error calls out is only available in the blevesearch org's fork of faiss.

I did use the advertised version.
I was finally able to make this work by using -DCMAKE_WINDOWS_EXPORT_ALL_SYMBOLS=ON flag when building faiss libraries on Windows. I found this while looking at other C# wrappers created to use faiss on Windows.
I am marking this as an answer for the original question.
